You can create a proof of existence and/or ownership for your authentic work, e.g. design, musical composition, code, movie script, or anything else that can be considered as intellectual property and falls under copyright protection law.

Valuable Content Archive
The Afterlife
Zorba the Buddha
Interesting or important content that can be stored permanently in the blockchain to make it available for future generations and to promote long-term thinking.

To prevent blockchain bloating and to avoid high transaction fee, the content needs to be relatively short. For a larger content, or files, the best practice is to include only the content's hash, and to publish the actual content somewhere else, e.g. on IPFS. See the FAQ for more details.
Resolutions, Declarations, Confessions and other Public Statements
First Things First Manifesto 2000
New Year's Resolution

Resolutions and declarations become more powerful when they are publicly available and there is no way to take them back. The one who made a statement is then obliged to follow on the promises. Additionally, you can claim something publicly, create an acknowledgment, or give a credit, create a permanent confession of love or record the fact of marriage.
PROOF OF EXISTENCE
The options for setting things in block are endless. By recording a file's hash in the blockchain, you can set in block virtually anything. The thing represented in the file, no matter the format, receives an immutable and incorruptible timestamp, which works as a proof-of-existence. Such proof never expires, it cannot be edited or deleted, and it can always be independently verified.
